Athens Twilight 2012 vs Sunny King 2012 power and heartrate data

Well, the results are in, and below is this year’s side-by-side comparison of two very popular pro criteriums (Sunny King and Athens Terrapin Twilight). I still don’t know how to decide which race is harder … so y’all look at the data and make some comments about how you interpret it. Thanks! This year’s races were held on back-to-back weekends with Sunny King held in Anniston, Alabama on Saturday, April 21st at 7:30PM and Athens Twilight held in Athens, Georgia on Saturday, April 28th at 9:00PM.

Some notes about the data … first, it was really windy for this year’s Sunny King criterium, which partially explains the higher power / lower average speed. But a bigger factor in the Watts vs Speed differences between the races is that in Athens you have a long stretch of the course where you rest … from the downhill going into Turn 3 all the way through Turn 4. The only place to rest on the Sunny King course is about 3 or 4 seconds as you brake hard into Turn #3.

Here are the power maps … note that for the Sunny King race there is a lot more time to warm up on the course so a lot of the purple lines are from my warm-up laps.

Here is a side-by-side on the lap data for the two races showing avg power, max power, and avg heartrate. Sunny King is on a slightly longer course so there is only 60 laps as compared to 80 laps for the Athens Twilight race.
